Abstract

Density is a predominant factor in the performance of powder metallurgy (PM) parts. High density materials are preferred because of their superior properties compared to low-dense materials. However, the tooling cost and geometry considerations limit the traditional compaction process from achieving higher densities. In this study, electromagnetic compaction was used as a secondary compaction process to provide additional densification for the much needed highdensity properties. The investigation was focused on the effects of electromagnetic compaction/compression on the density, microstructure, and mechanical properties of two variants of sintered steel PM compacts, FL-5305 and FY-4500. The results show that electromagnetic compression was more effective for densification of FL-5305 parts than for FY-4500. Also noted was the increase in the microhardness of electromagnetic compressed FL-5305 in comparison to as-sintered parts.
